elliptic theta function | eta function

The Jacobi theta functions are the elliptic analogs of the exponential function, and may be used to express the Jacobi elliptic functions. The theta functions are quasi-doubly periodic, and are most commonly denoted ϑ_n(z, q) in modern texts, although the notations Θ_n(z, q) and θ_n(z, q) are sometimes also used. Whittaker and Watson gives a table summarizing notations used by various earlier writers. The theta functions are given in the Wolfram Language by EllipticTheta[n, z, q], and their derivatives are given by EllipticThetaPrime[n, z, q]. The translational partition function for an ideal gas can be derived using elliptic theta functions.
